Photoexcited Hole States at the SrTiO3(001) Surface Imaged with Noncontact AFM
Igor Sokolovic, Florian Ellinger, Aji Alexander +8
The behaviour of excess charges in ionic lattices, such as the formation of polarons and charge trapping at defect sites, influences the physical and chemical properties of materia…
How to cleave cubic perovskite oxides
Igor Sokolović, Michael Schmid, Ulrike Diebold +1
Surfaces of cubic perovskite oxides attract significant attention for their physical tunability and high potential for technical applications. Bulk-terminated surfaces are desirabl…
Duality and degeneracy lifting in two-dimensional electron liquids on SrTiO(001)
Igor Sokolović, Eduardo B. Guedes, Thomas P. van Waas +7
Two-dimensional electron liquids (2DELs) have increasing technological relevance for ultrafast electronics and spintronics, yet significant gaps in their fundamental understanding…
Real and Reciprocal Space Characterization of the 3-Dimensional Charge Density Wave in Quasi-1-Dimensional CuTe
Fei Guo, Michele Puppin, Lukas Hellbruck +4
Low-dimensional materials are susceptible to electronic instabilities such as charge density waves (CDWs), originating from a divergence in the Lindhard electron response function,…
Machine Learning Based Prediction of Polaron-Vacancy Patterns on the TiO(110) Surface
Viktor C. Birschitzky, Igor Sokolovic, Michael Prezzi +5
The multifaceted physics of oxides is shaped by their composition and the presence of defects, which are often accompanied by the formation of polarons. The simultaneous presence o…
Interaction of surface cations of cleaved mica with water in vapor and liquid forms
Giada Franceschi, Sebastian Brandstetter, Jan Balajka +5
Natural minerals contain ions that become hydrated when they come into contact with water in vapor and liquid forms. Muscovite mica -- a common phyllosilicate with perfect cleavage…
Resolving the intrinsic short-range ordering of K ions on cleaved muscovite mica
Giada Franceschi, Pavel Kocán, Andrea Conti +8
Muscovite mica, KAl(SiAl)O(OH), is a common layered phyllosilicate with perfect cleavage planes. The atomically flat surfaces obtained through cleaving lend them…
Water Structures Reveal Local Hydrophobicity on the In2O3(111) Surface
Hao Chen, Matthias A. Blatnik, Christian L. Ritterhoff +9
Clean oxide surfaces are generally hydrophilic. Water molecules anchor at undercoordinated surface metal atoms that act as Lewis-acid sites, and they are stabilized by H bonds to u…
Real-space investigation of polarons in hematite Fe2O3
Jesus Redondo, Michele Reticcioli, Vit Gabriel +17
In polarizable materials, electronic charge carriers interact with the surrounding ions, leading to quasiparticle behaviour. The resulting polarons play a central role in many mate…
Automated Real-Space Lattice Extraction for Atomic Force Microscopy Images
Marco Corrias, Lorenzo Papa, Igor Sokolović +7
Analyzing atomically resolved images is a time-consuming process requiring solid experience and substantial human intervention. In addition, the acquired images contain a large amo…
Does a pristine, unreconstructed SrTiO(001) surface exist?
Igor Sokolović, Giada Franceschi, Zhichang Wang +6
The surfaces of perovskite oxides affect their functional properties, and while a bulk-truncated (11) termination is generally assumed, its existence and stability is contr…
Defect chemistry of Eu dopants in NaI scintillators studied by atomically resolved force microscopy
Manuel Ulreich, Lynn A. Boatner, Igor Sokolovic +6
Activator impurities and their distribution in the host lattice play a key role in scintillation phenomena. Here a combination of cross-sectional noncontact atomic force microscopy…
Incipient ferroelectricity: A route towards bulk-terminated SrTiO3
Igor Sokolovic, Michael Schmid, Ulrike Diebold +1
Perovskite oxides attract increasing attention due to their broad potential in many applications. Understanding their surfaces is challenging, though, because the ternary compositi…
Interplay between adsorbates and polarons: CO on rutile TiO(110)
Michele Reticcioli, Igor Sokolović, Michael Schmid +3
Polaron formation plays a major role in determining the structural, electrical and chemical properties of ionic crystals. Using a combination of first principles calculations and s…
